Chapter 4, Problem 19E

Explanation of Solution

Program:

//define the static function

public static int quadrant(double x, double y) {

    //condition initialized to check whether the value of x and y are greater than zero

    if (x > 0 && y > 0) {

        //return statement

        return 1;

      //condition initialized to check whether the value of x is lesser than zero and y is greater than zero  

    } else if (x < 0 && y > 0) {

        //return statement

        return 2;

      //condition initialized to check whether the value of x is lesser than zero and y is lesser than zero  

    } else if (x < 0 && y < 0) {

        //return statement

        return 3;

      //condition initia...
